Summary
Python 3.12 reaches end of life in October 2028, according to PEP 693 and the official Python release-cycle data. It is already in the security-fix-only phase, so it no longer gets regular bug-fix releases.
Python 3.12 key dates
- First release: 2 October 2023
- Status now: security fixes only
- End of life: October 2028
What security-only means
Only security patches are applied, released as source-only versions without binary installers.
Upgrade path
Python 3.13 and 3.14 are both supported. If you are still on 3.11, which ends in October 2027, moving straight to 3.13 or 3.14 gives you a longer runway.
